摘要
目的:了解二氧化氯(ClO2)溶液的稳定性,观察ClO2消毒剂对坑道水库储水的消毒效果,为战时或特殊情况下坑道内饮用水卫生保障提供依据。方法:实验室试验观察ClO2溶液的稳定性,现场模拟试验观察ClO2消毒效果,水库现场消毒观察ClO2实际应用情况。结果:根据储水量按5 mg/L ClO2对坑道水库储水进行消毒,消毒后90天ClO2浓度下降至0.01 mg/L,细菌总数、真菌数及大肠菌群均未检出,消毒效果满意。结论:5 mg/L ClO2消毒储水,在坑道阴暗、低温且避光的环境中90天消毒效果好,适合坑道储水短期消毒。
Objective：To understand the stability of chlorine dioxide（ClO2） solution,observe the disinfection effect of ClO2 for storage water in tunnel,and provide a basis for safe drinking in wartime or special conditions.Methods： Observe the stability of ClO2 solution in laboratory,the disinfection effect by model experiment,and the in-service use in reservoirs.Results： Disinfected the storage water in tunnel using ClO2 in 5 mg/L,90 days later,the concentration of ClO2 turned to 0.01 mg/L,total bacteria and coli group couldn′t be found,the disinfection effect was satisfactory.Conclusion： The effect of disinfection for storage water with 5 mg/L ClO2 in tunnel,a dark wet and out of light environment,was satisfactory for 90 days,it was sutiable for short-term disinfection.
